Experimental Study on Dust Explosion of Expanded Ammonium Nitrate Explosive

Expanded ammonium nitrate explosive(EANE) is a common industrial explosive.Dust explosive hazard of EANE was investigated by 20 L explosion chamber test,with corn starch compared.The results show that the possibility of dust explosion of EANE is very small,and dust explosion will not happen in the concentration from 50 g/m3 to 1100 g/m3,while corn starch dust has the danger of dust explosion.These results provide great reference for the safe production and usage of them.
